0004149: FileServlet range handling with firefox
(rep by Fred Howell)

Just ran into a FileServlet issue on resin 4.0.9 serving up a
500kb pdf file staticly - looks like it's a http range issue. Only shows up on firefox (using v3.6.8) - IE7, Safari, Opera,
Chrome (and wget using http1.0) work fine. Also tiny files are served
fine on firefox.

Could well be a firefox http range bug, but it does happen in a vanilla
install of resin, so I thought you'd like to know - to reproduce the issue:
  Copy a 500kb+ pdf into webapps/ROOT (the one I used was: [^] )
  Point firefox at localhost:8080/welcome.pdf

--- log snippets:

jvm-default.log has:
 [10-07-30 18:18:50.171] {http://*:8080-2} [^] java.lang.NullPointerException
                                               at com.caucho.servlets.FileServlet.handleRange(
                                               at com.caucho.servlets.FileServlet.service(

The line in FileServlet,java is:-
   if (hasMore) {
     os.write('\r'); <---

Firebug shows the request headers as below - response is a 500 internal server error.
